SVC is a dynamic reactive compensator based on switching type HV electrical and electronic devices, well recognized as an effective means of resolving power quality problems. SVC is complex in structure, consisting of TCR valve sets, FC filter channel, etc. In particular, TCR valve set adopts thyristor serial connecting technology, and over 100 thyristors are adopted, which requires real-time status of devices in SVC to be monitored and uploaded, and even failures to be recorded. Therefore, the monitoring software becomes an important part in ensuring SVC safe operation. Combined with actual cases, this paper introduces a technology of using C++ Builder and Inter Base to design the static reactive compensator monitoring software. The user interface is elegant, with short development period, highly transplantable, and easily modified.

Designed the control system policy for automobile electric seat using fuzzy control technology, therefore established its control model by Fuzzy Logic Toolbox, and carried on the off-line simulation to choose controller's optimum control parameters. From the dynamic viewpoint, the auto electric seat adjustment system is not only a complex nonlinear function which includes the location of the DC servo motor and the speed, but also contains serious nonlinear coupling interference, so the system is a highly nonlinear strong coupling, variable multivariable system. Application of traditional control methods (such as traditional PID) is difficult to meet its order requirements, so the research is highly robust method of intelligent control is an effective way to solve the problem. Fuzzy control technology has become the field in which drawn greater attention and researched in recent years. It doesn’t depend on the mathematical model of controlled object, has a good robustness, and nonlinear control characteristics, so it is an effective means to control the object with time-varying, non- linear parameters. In this paper, fuzzy control technology to achieve the orders of auto electric seat adjustment control system functions in the Literature [1], and the tracking of the system was simulated.

AbstractMost deposition chambers sold into the optical coating market today are outfitted with an automated control system. We surveyed several of the larger equipment providers, and nine of them responded with information about their hardware architecture, data logging, level of automation, error handling, user interface, and interfacing options. In this paper, we present a summary of the results of the survey and describe commonalities and differences together with some considerations of tradeoffs, such as between capability for high customization and simplicity of operation.

Gate oxide reliability of a trench-gate SiC MOSFET can be improved by incorporating a gate protection structure, but the resulting parasitic JFET resistance is one major drawback. For reduction of on-resistance, a new method of localized high-concentration n-type doping in JFET regions (JD) is developed. Utilizing process and device simulation by TCAD, the optimal condition of JD that enables maximum device performance is derived. By fabricating a device with the optimal JD structure, the on-resistance is successfully reduced by 25% compared to a conventional device without JD, while maintaining the withstand voltage and the gate oxide electric field at the same level. As a result, a device exhibiting a specific on-resistance of 1.84 mΩcm2 and a breakdown voltage of 1560 V is obtained. The optimal JD structure maintains the short-circuit safe operation area comparable to that for the structure without JD. Thus, by reducing the JFET resistance while minimizing effects on other characteristics, localized JD is shown to be an effective means of realizing a reliable, low-resistance SiC power device.
